Hello Guido
I am very familiar with the procedure.
Although I can’t understand why, Switzerland didn’t go along with the EU when it came to abolishing roaming fees, since Switzerland otherwise attaches such great importance to EU conformity.
Now it’s just the case that as a customer I’m looking for the best price/performance ratio for me. During the (EU) holidays I’m clearly best off with a prepaid payment from the relevant country (thanks to EU regulations). It is the right of every customer to purchase the services wherever they want them. If the provider cannot sell his products, he should consider whether he still offers timely products. The Swiss are very sluggish when it comes to price elasticity, so such a policy may last longer here.
Your word in God’s ear that you can also load foreign pre-paid as an e-Sim onto (Swisscom branded) devices.
Until I have tested this, I will continue to pay attention to dual-SIM operation devices when purchasing devices and program myself what which SIM card should do what, or not.
